摘　　要：采用二维弹塑性有限元法进行了基坑开挖对临近桩基性状影响的数值模拟,分析了基坑开挖所引起的临近桩基周围土体变形场的特性,讨论了不同开挖深度对桩身水平位移和弯矩的变化特性,得出了一些对工程实践有理论指导意义的结论。The paper carries out the numerical simulation on the impact of foundation excavation upon neighborhood pile foundation performance by using two-dimensionrl elastic-plastic finite element method, analyzes the soil deformation characteristics surrounding the neighborhood pile foundation owing to the foundation excavation, discusses horizontal pile displacement and bending moment varying features of various excavation depths, and finally draws some theoretically guiding conclusions for the engineering practice.
